Purpose
The aim of the study was to assess whether combined and compound morning training (CCMT) can improve hormonal and metabolic profiles in healthy male students.
Methods
Eighty-three male students were randomly put into two groups: experimental (n = 42) and control (n = 41). The experimental group participated in the selected (aerobic, balance, resistance and stretch) exercises with moderate intensity for 16 weeks, four sessions per week, a 40 min workout in the morning. Salivary testosterone and cortisol, serum adiponectin, insulin and lipid profile were determined in both groups before and after the intervention.
Results
Four months of training caused an increase in testosterone (85 ± 9.4 vs. 93 ± 9.7 pg/ml), adiponectin (11.35 ± 2.00 vs. 12.86 ± 1.97 ng/ml) and testosterone/cortisol ratio (0.006 ± 0.003 vs. 0.009 ± 0.004), as well as a reduction in cortisol (16.3 ± 6.15 vs. 12.4 ± 4.85 ng/ml) and insulin resistance (2.15 ± 0.52 vs. 1.79 ± 0.34), for the experimental as compared to their baseline data (P value <0.001). Furthermore, a moderate correlation between testosterone and adiponectin was revealed (r = 0.31, P value = 0.04).
Conclusions
This new training strategy successfully and meaningfully improved hormonal and metabolic parameters. The research proposed that CCMT can promote anabolic pathways. Favourably, the programme could be considered as a testosterone enhancer and cortisol reducer simultaneously.
